Set Optiplex vPro Manageability Option

Mark Berry July 16, 2012

Almost four years ago, I blogged about how to buy an OptiPlex with vPro from the Dell Outlet. Unfortunately the last time I checked, Dell no longer publishes the detailed system information before you purchase, though you might be able to get the info from a salesperson.


Dell PERC 5/i Battery Needs Replacing

Mark Berry June 30, 2012

On a Dell PowerEdge 1900, I was noticing in the OpenManage Alert log that the disk cache policy kept “bouncing” between Write Through and Write Back.


Manage and Monitor Dell PERC RAID under Linux

Mark Berry February 17, 2012

I’ve repurposed an old Dell PowerEdge 1500SC with a PERC 3/SC RAID card for use as a Linux phone server running Asterisk. Unfortunately, the only version of Dell OpenManage that works for the 1500SC (OpenManage 4.5 docs and download) is only supported under Redhat 7.1. I’m using CentOS 5.2, so I’m out of luck.

I eventually found that I could use Linux tools for the LSI MegaRAID SCSI 320-1LP to control and monitor the PERC 3/SC. Visit this download page and search for “OS: Linux”.


Monitor Dell DRAC 5 Using SNMP

Mark Berry March 2, 2011

I want to use the SNMP checks in GFI MAX Remote Management to monitor my Dell Remote Access Controller (DRAC), version 5. The Dell™ OpenManage™ Server Administrator Version 6.2 SNMP Reference Guide (PDF) is the main reference on Dell SNMP.



PowerEdge 1500SC: Bogus Memory and Linux Errors

Mark Berry November 1, 2010

Sometimes the trickiest errors are the ones you should ignore.

I’m running PBX in a Flash, based on CentOS 5.2, on a Dell PowerEdge 1500SC. Back in February, I got a segmentation fault error and after some discussion on the PBX in a Flash forum, concluded that I needed to replace the hardware or at least the memory. Now I’m not so sure.


Windows 7 UAC Blocks DRAC II Web Console

Mark Berry October 22, 2010

You have an old Dell server with a DRAC II remote access card. You just installed Windows 7 and you want to control the DRAC II from that desktop. You’ve installed the Dell Management Station and Client Web Console on the Windows 7 machine. When you run the DRAC II Client Web Console, the ActiveX component starts fine, but once you try to connect to the server, you get this message:


Fixing DRAC 5 Error: Remote Access Controller initialization failure

Mark Berry March 4, 2010

I recently got a good eBay deal on a DRAC 5 remote access card for my Dell PowerEdge 2900 server.

Well it seemed like a good deal until I installed the card and got this message on bootup:

Remote Access Controller detected
!!*** Error: Remote Access Controller initialization failure***

Monitor Bandwidth with PRTG and a PowerConnect 2824 Switch

Mark Berry January 3, 2010

The previous post described basic setup of the Dell PowerConnect 2824 switch. One of the reasons I bought this switch is its ability to “mirror” a port. This allows a properly-configured computer to sniff all the packets going through the mirrored port. If you mirror the port that goes to your external router, you should be able to monitor all the traffic between your router and all internal computers.

Setting up the switch and the free PRTG Network Monitor was pretty easy. Setting up the computer itself (an old Windows XP Home box) took some fiddling. Here in brief are the steps.
